The four parts of a quadrant are upper right, upper left, lower right, lower left.
The upper right quadrant of the coordinate plane, sometimes known as quadrant 1, has only positive coordinates (QI). Quadrant two is the upper left-fourth of the coordinate plane (QII). Quadrant three is at the bottom left (QIII). Located in the bottom right corner is quadrant number four (QIV). In quadrant I, the x- and y-coordinates are both positive. In quadrant II, the x-coordinate is negative while the y-coordinate is positive. In quadrant III, the x- and y-coordinates are positive. In quadrant IV, the x-coordinate is positive while the y-coordinate is negative. The area enclosed by the x and y axes is referred to as a quadrant in a coordinate system.

Where would the intensity of an earthquake be higher?.
The intensity of an earthquake generally higher near the epicenter.
Intensity is based on observed effects of ground motion on people, buildings and natural features. This varies from site to site within the fault region, depending on the observer's position relative to the earthquake epicenter. The seismic intensity of an earthquake decreases as the distance from the epicenter increases, and decreases as the distance from the epicenter increases. An epicenter is a point on the surface of the Earth directly above where an earthquake begins. Earthquakes with a moment magnitude of approximately 6.5 or less occur in a concentrated area directly below the epicenter. Therefore, apart from the effects of different rock types and different soil types, the greatest shaking occurs at the epicenter. Earthquakes with a moment magnitude greater than 6.5 cause faults at some distance from the epicenter. At these large sizes, it is common for fractures to reach the surface. In such cases, the maximum shaking may or may not occur at the epicenter..

The equation that represents circles that have a diameter of 12 units and a center that lies on the y-axis is x²+ (y-3)² = 36
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, a circle have a diameter of 12 units and a center that lies on the y-axis, we need to find its equation,
We know that, the standard form of the equation of a circle is expressed as;
(x-a)² + (y-b)² = b=r²
where;
(a, b) is the center of the circle
r is the radius of the circle
We have,
diameter = 12 units
radius = 12/2 = 6 units
If the center lies on the y-axis, the center will be at (0, 3)
Substituting into the formula, we will have (x-0)² + (y-3)² = 6²
x²+ (y-3)² = 36

Sam ued to be 175cm tall. He i now 7% taller. To the nearet centimeter,how tall i Sam now
Sam is now 187cm tall. When we say that Sam is now 7% taller, it means that his new height is 7% greater than his original height.
To find out how much taller he is, we can calculate 7% of his original height using the percentage formula:
percentage of original value = (part / whole) * 100
In this case, the part is the increase in height, and the whole is the original height. To find the part, we can rearrange the formula to:
part = (percentage / 100) * whole
So, to find the increase in height, we can substitute the values we know:
increase in height = (7 / 100) * 175 cm
This simplifies to:
increase in height = 12.25 cm
Now that we know how much taller Sam is, we can add this increase to his original height to find his new height:
new height = original height + increase in height
new height = 175 cm + 12.25 cm = 187.25 cm
So, Sam is now 187.25 cm tall. This number is rounded to the nearest centimeter, so his new height is 187cm tall.

What is the first step for solving the system using substitution results in an equation?.
The first step for solving the system using substitution results in an equation is solve one equation for either x or y.
The substitution method is a quick and easy way to algebraically solve a set of linear equations and determine the variables' solutions. According to what the name implies, this method entails determining the value of the x-variable in terms of the y-variable from the first equation and then substituting or replacing the value of the x-variable in the second equation.
We can solve and determine the value of the y-variable in this method. Finally, we may use any of the above equations to obtain x by substituting the value of y. This procedure can also be switched around so that we first solve for x before solving for y.

Speed is the rate of change of an object's position relative to a given frame of reference. It is a scalar quantity, meaning it has both magnitude and direction. Speed is usually measured in meters per second (m/s) or kilometers per hour (km/h). Speed is an important factor in many activities, including travel, sports, and transportation.
This can be calculated by multiplying the speed of light (3.0 x 108 m/s) by the time (12.3 nanoseconds), which yields a result of 37.9 meters. This answer is rounded to the correct number of significant figures, which is two.

What is the perfect square trinomial of 36?.
A perfect square trinomial is a polynomial of the form (x + b)^2 = x^2 + 2bx + b^2. It is called a "perfect square" because when it is multiplied out, the resulting polynomial is a square of a binomial.
To find the perfect square trinomial of 36, we need to find two numbers that when added, give us b and when multiplied give us b^2=36.
Those two numbers are 6 and -6, since 6*-6 = -36 = 36.
So, the perfect square trinomial of 36 is (x + 6)(x - 6) = x^2 - 36
Another way to find the perfect square trinomial is to take the square root of the constant term (36) and then add and subtract that value to the variable.
√36 = 6
then x^2 + 6x - 6x + 36 = x^2 - 36

A cell phone company charge 50$ for a phone plu 25$ per month. You get a gift card for 100$. When doe the total pent on your phone ervice exeed the amount on you gift card?
The money spent on a phone plan can be represented by the inequality:
50 + 25x > 100 and the total money spent on the phone service exceeds the amount of the gift card after the 2nd month.
In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
The inequality represents the total cost of the phone plan, where x represents the number of months for which the service is used.
The first part of the inequality, 50$, represents the initial cost of the phone.
The second part, 25x, represents the monthly cost of the service, 25$ per month.
So, the inequality represents the total cost of the phone plan as the sum of the initial cost of the phone and the monthly cost of the service for x number of months.
50 + 25x > 100
It states that the total cost (50 + 25x) of the phone plan is greater than 100$.
It's the total cost you have to pay for the phone and the service.
It's used to know when the total cost exceeds 100$, which is the gift card's value.
To find out when the total spent on the phone service exceeds the amount of the gift card, we can substitute in the inequality with the given values and solve for x.
50 + 25x > 100
x > (100-50)/25
x > 2
So, the total spent on the phone service exceeds the amount of the gift card after the 2nd month.
Therefore, The money spent on a phone plan can be represented by the inequality : 50 + 25x > 100 and the total money spent on the phone service exceeds the amount of the gift card after the 2nd month.

So, the y-value of the solution to the system of equations 3x + 5y = 17 and 4x + 4y = -13 is not possible to find, because the system is inconsistent and has no solution.
To find the y-value of the solution to the system of equations 3x + 5y = 17 and 4x + 4y = -13, we can use one of the methods for solving systems of equations, such as substitution, elimination, or graphing. In this case, we will use elimination method.
The first step of elimination method is to eliminate one of the variables by adding or subtracting the equations. In this case, we will multiply the first equation by 4 and the second equation by -3 and add them:
4(3x + 5y) = 4(17)
12x + 20y = 68
-3(4x + 4y) = -3(-13)
-12x - 12y = 39
then we can add these two equations:
12x + 20y = 68
-12x - 12y = 39
0 = 29
This is an impossible equation, which means that the system has no solution.
